Maintaining signals is a partnership

CDOT owns and operates signals along U.S. Highway 85, including the segment between U.S. 85 and I-25, known as Meadows Parkway. It also owns the signals on State Highway 86 between I-25 and Fifth Street, known as Founders Parkway, which runs east through Town.

The Town maintains all other signals within Town limits.

Reporting a concern

If you see a signal is malfunctioning, call Castle Rock Police dispatch, 303-663-6100.

When is a traffic signal installed?

Engineering studies determine the most appropriate location and mode of operation for the signal. As with stop signs, specifications for signals and their placement as well as minimum requirements for their installation and use are contained in the Manual on Uniform Traffic Control Devices.

Federal and state regulations require that the installation of any traffic signal follows the guidelines in this manual. Signals are installed using various funding sources, including federal funding, property tax dollars and development fees. A new traffic signal costs approximately $250,000, so its installation must be carefully considered. An ill-advised or poorly designed signal is not only annoying, it also can be dangerous to pedestrians, cyclists and drivers.
